Specification of Letters Patent.

Patented June 2'7, 1916.

Application filed December 30, 1909, Serial No. 535,658. Renewed May 3,1916. Serial No. 95,251.

To all whom it may concern Be it known that I, NELSON MUsLAR, a citizenof the United States, residing at Worcester, in the county of Worcesterand State of lVIassachusetts, have invented a new and useful Improvementin Labeling-Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to machines for pasting labels on bottles or otherreceptacles of similar form.

One object of the invention is to produce a labeling machine which willbe capable vibration and consumption of power, and to this end Iemploymechanisms for actuating the label pickers and wipers arranged tomove these parts in opposite directions at the same time so as tocounterbalance and neutralize the tendency of these parts to producevibrations in the machine owing to their respective movement.

Another object of the invention is to provide a bottle-labeling machinewith improved means for supplying adhesive to the label pickers, and tothis end I employ a pump of novel construction and arrange ment whichwill be more particularly described hereinafter.

A third object of the invention is to produce improved devices forholding and feeding the labels, the label-holding devices being capableof adjustment for different sizes of labels and such adjustment beingaccomplished without change in the general position in which the labelis applied to the bottle.

Other objects and features of my invention will be set forth inconnection with the description of the illustrated embodiment of theinvention.

In the accompanying drawings, which illustrate the preferred embodimentof my invention, Figure 1 is a side elevation of the labeling machinecomplete; Fig. 2 is a front elevation of a portion of the machine, thelabel holding devices and the base portion of the same being omitted;Fig. 3 is a vertical section of the machine taken on the median planelooking from right to left; Fig. 4 is a plan view, showing in detail thelabel holding devices; Fig. 5 is a section on line 55 in Fig. 4; Fig. 6is a section, on an enlarged scale, on line 6-6 in Fig. 3, showingparticularly the construction of the adhesive pump and valve; and Fig. 7is a section of the driving clutch on line 77 in Fig. 8.

The operative instrumentalities of the illustrated embodiment of myinvention comprise a bottle rest 8 upon which the bottle is supportedduring the labeling operation, label-holding devices by which stacks oflabels 9 and 10 are held above the bottle rest, label pickers l1 and 12by which the labels are transferred from the label-holdof operating athigh speed without excessive I ing devices to the bottle and by whichthe paste is applied to the edges of the labels, a clamp 13 by which thelabels are held in place upon the bottle, and two wipers 14 by which thelabels are pressed smoothly upon and secured to the. bottle. The machineis also provided with a member 15 which serves both as a gage todetermine the position of the bottle on the bottle rest and as anelement of automatic mechanism for setting the machine into operationwhen a bottle is placed in position on the rest.

The bottle rest 8 has a concave upper surface adapted to center thebottle in the machine when laid upon its side on the rest, as shown inFigs. 1 and 3. The rest is mounted with a vertical tongue-andslotconnection upon a bracket 16 constituting a portion of the frame of themachine, and by means of an adjusting screw 17 the bottle rest may beadjusted vertically to compensate for differences in the diameters ofthe bottles operated upon.

The label pickers 11 and 12 are similar in construction to thoseillustrated in Letters Patent No. 82 L569, granted to me June 26, 1906,being hollow and provided upon their operative surfaces withperforations through which paste or other adhesive is fed. In thepresent machine the operative surfaces of the pickers are directedupwardly and are substantially horizontal, as shown in Figs. 2 and 3.

The label pickers are mounted upon hollow stems 18 at either side of theposition occupied by the bottle, and the stems 18 project forwardly fromtwo upwardly-extending arms 19 connected at their lower ends by a yoke20. The yoke 20 is arranged to move vertically so as to raise and lowerthe label pickers, and to this end it is mounted upon two vertical sliderods 21 which move in guides 22 on the frame of the machine.

The adhesive is supplied to the label pickers by means of a pump whichis carried by the yoke 20 so as to participate in its ver ticalmovements. The pump cylinder 23 is supported by two rods 24- connectingit rigidly with the yoke 20. A reservoir 25 is fixed to the front of thepump cylinder, carries the supply of adhesive, and it is connected withthe pump cylinder by a passage 2G controlled by a valve 27. The valve 27also controls an outlet passage 28 through which the adhesive is pumpedinto two vertical tubes 29. The tubes 29 connect the pump with thehollow stems 18, and thus adhesive is conducted from the pump to thelabel pickers.

The pump piston 30 is provided with a piston rod 3lwvhich extendsdownwardly from the pump cylinder and passes loosely through an openingin the lug 32 on the frame of the machine. Adjustable stop nuts 33 and34 are arranged upon the piston rod 31 above and below the lug 32. Thisarrangement is such as to permit the pump piston to be actuated throughthe vertical movement of the pump cylinder with the yoke 20, but with astroke considerably less than the amplitude of movement of the yoke andthe label pickers. Throughout the greater part of the vertical movementsof the pump cylinder the piston moves with the cylinder and isinoperative, but, shortly before the extremity of the upward movement isreached, the stop nuts 34 engage the lower surface of the lug 32 andcause the piston to be drawn downward in the cylinder for a shortstroke, of which the length may be adjusted by changing the position ofthe stop nuts 34 on the piston rod. The piston is moved in the oppositedirection by the engagement of the stop nuts 33 with the lug 32 shortlybefore the extremity of the downward movement of the pump cylinder.

The valve 27 connects the pump cylinder with the outlet passage 28during the outward stroke of the piston so asto cause the adhesive to beforced into the tubes 29, and it connects the pump cylinder with theinlet passage 26 during the inward stroke of the piston to cause theadhesive to be drawn from the receptacle 25 into the pump cylinder. Thevalve is actuated by means of two arms and 37 carried at one end of thevalve in position to engage a pin 36 projecting inwardly from one of theguides 22-. During the upward movement of the pump this pin engages anddepresses the arm 37 so as to move the valve into position shown in Fig.3, while during the downward movement of the pump the pin engages andelevates the arm 35 so as to move the valve through aquarter-revolution, thus closing the passage 28 and connecting thepassage 26 with the pump cylinder.

The above-described arrangement of the pump avoids the necessity offlexible connections between the label pickers and the pu1np,'or betweenthe pump and adhesive receptacle, thereby increasing the durability ofthe mechanisms and the positiveness of the feeding action upon theadhesive. The adhesive supplied by the pump at each stroke exudes uponthe label surfaces of the label pickers through the openingshereinbefore described.

The labels 9, which are applied to the bodies of the bottles, are heldin the label holder which comprises two vertical members 41 and 42 whichengage the front and rear edges of the stack of labels. These membersare adjustable toward and from each other to adapt the label holder tolabels of different sizes, and for this purpose the members 41 and 42are mounted to slide upon two parallel horizontal rods 43 which projectforward from a. yoke 44 mounted upon the frame of the machine. Themembers 41 and 42 are moved, for the purpose of such adjustment, bymeans of-a rightand-left-hand screw 45, having threaded engagement withthe said members, and provided with a hand wheel 46 by which it may beturned. The members 41 and 42 are provided at their lower extremitieswith narrow lips 47 which engage the labels at their edges and serve tosupport the labels in the holder without preventing the removal of thelowermost label by the label pickers.

The ends of the labels are engaged and positioned by vertical guides 48which are fixed to arms 50, slidably mounted upon transverse horizontalguide rods 51. The guide rods 51 are fixed upon laterally-extending armson the yoke 44. The end guides 48 are adjusted to accommodate labels ofdifferent lengths by moving the arms 50 upon the guide rods 51, and forthis purpose the arms are engaged by a right-and-lefthand adjustingscrew 52, provided with a hand wheel 53 by which it may .be turned. Theend guides are also provided with narrow lips 49 to retain the labels inthe holder.

When the label pickers rise in the operation of the machine, the pickers11 move into engagement-with the lowermost label 9 in the label holder,and the adhesive upon the surfaces of the pickers is thus applied to themarginal portions of the label at its ends. lVhen the pickers 11 fallagain, the label adheres to the pickers and is drawn out the bottom ofthe label holder. The other labels are retained in the holder bv meansof the lips 47 and 49. The label thus withdrawn is laid across the uppersurface of the body of the bottle by the downward movement of thepickers, and is then in position to be pressed against and secured tothe bottle by the wipers.

To insure the feeding of the labels from the label holder, a follower inthe form of a plate 54 is laid upon the top of the stack of labels. Theweight of the follower is suffi- ,cient to insure the regular downwardmovement of the labels as they are removed one by one, while notsuflicient to press them so firmly. against the lips as to substantiallyresist the withrawal of the lowermost label in the manner hereinafterdescribed. To insure the adhesion of the lowermost label to the pickersand the application of the adhesive to this label, it is desirable thatthe pickers be pressed against the label with a force greater than thatnecessary to raise the follower 54, and for this reason the fol lower isprovided with means for resisting the upward movement of the followerwhen the pickers engage the lowermost label. To this end vertical rods55 are mounted .on the arms 50 and are provided with toothed innersurfaces. Guides 56 slide freely upon the rods 55, and pawls 57 arepivoted on the guides in position to engage the toothed surfaces of therods 55. These pawls carry spring-pressed plungers 58 which bear againstthe upper surface of the follower 54. The pawls and guides follow thefollower in its downward movement as the height of the stack of labelsdiminishes, but whenever the follower tends to rise under pressure ofthe pickers against the bottom of the stack the pawls 57 are moved intoengagement with the rods 55, which prevents their upward movement. Theplungers 58 then act to resist the upward movement of the follower,while the springs by which these plungers are pressed downwardly permitsufficient yielding of the follower to prevent the production of unduepressure between the pickers and the labels.

The machine is provided with a second label holder adapted to holdlabels to be applied to the neck of the bottle by the pickers 12. Theneck-label holder has end guides 60 which engage the ends of thecrescent-shaped neck labels and which are provided with lips at theirlower extremities for the purpose hereinbefore referred to. A

'front guide is also provided to engage the middle of the front edges ofthe neck labels. The end guides 60 are mounted on arms 61 which areadjustably secured to a cross-bar 62 by means of screws 63. Uponloosening these screws the arms 61 may be moved horizontally upon thebar 62, so as to be adjusted to hold and receive labels of differentlengths. The crossbar 62 is mounted upon forwardly-extending horizontalrods 64 fixed on the yoke 44. By moving the cross-bar 62 forwardly orrearwardly on the rods 64 the position in which the neck label isapplied to the bottle may be adjusted,

The neck-label holder is provided with a follower 66 which is controlledby a pawl mechanism comprising pawls 67 and rods 68 similar in functionand construction to pawls 57 and rods 55 hereinbefore described. Thelabel pickers 12 operate upon the neck labels 10 in the same manner thatthe label pickers 11 operate upon the body labels 9.

The label holders are filled by inserting the labels through the openbottoms of the holders, and to facilitate this operation the labelholders are arranged to be inverted so that the labels may be droppedinto them. For this purpose the yoke 44 is pivoted upon a stem 71projecting forwa'i'dly from a head 76. The yoke is normally preventedfrom turning on the stem by means of a tongueand-slot connection 69between the yoke and the head, and by a set screw which engages the stemand which is provided with a head 72 by which it may be turned. Vhen itis desired to invert the label holder the set screw is loosened and theyoke is drawn forward on the stem to disengage the tongueand-slotconnection. When the label holders are so inverted the followers aredepressed by manipulating the pawls to dis-' engage them from thetoothed rods, and the label holders may then be conveniently filled withlabels.

In adjusting or repairing the machine it is frequently convenient tomove the label holders from their position above the other parts of themachine, and to permit this to be done readily without removing thelabel holders entirely from the machine the head 76 is pivotally mountedupon a pin 73 fixed in the frame of the machine. on the head normallyengages a lug 75 on the frame to support the label holders in horizontalposition. To prevent the label holders from being pushed upwardly by theaction of the label pickers the head 76 is provided with an uppershoulder which normally engages an abutment 77 pivotally mounted upon apin 78 on the frame of the machine. A sliding spring-pressed latch 79 inthe abutment engages a recess in the shoulder on the head 76 andmaintains the abutment in engagement with the shoulder. By means of alaterally-projecting pin 80 the latch 79 may be retracted and theabutment 77 may then be swung back and out of engagement with theshoulder on the head 7 6 to permit the label holders and theirsupporting mechanisms to be swung upwardly and away from the partsbelow. The label holders are supported in raised position by a stop pin81 engaged by the shoulder on the head 76.

After the labels have been laid across the upper surface of the bottleby the label pickers they are temporarily held in place by the clamp 13.This clamp is provided with a central bottle-engaging portion 82 of Ashoulder 74 rubber or other flexible material and is formed to engageboth the body and the neck of the bottle. The clamp 13 is slotted on itsupper surface to engage a lever 83 upon which the clamp is supported,and the clamp and lever are connected by a pin 85 loosely engaging anopening in the lever and secured therein by a cotter pin, as shown inFig. 3. Springs 84 are provided between the clamp and lever to permitthe clamp to yield slightly when in engagement with the bottle. The rearend of the lever 83 is supported by a block 86 secured to the frame ofthe machine, the lever being provided with a longitudinal slot to permitit to be thrown forward and back on said block 86.

The clamp lever 83 and clamp are actuated by a bell-crank lever 87 whichis pivoted at one end to the lever 83 and is pivotally mounted at 88 onthe frame of the machine. The other arm of the bell-crank lever isconnected by a link 89 with a lever 90 pivoted upon the frame of themachine, and the lever 90 is connected by a link 91 with a slide 92moving vertically in a guideway on the frame of the machine. The slide92 carries a cam roll 93 which engages a cam path in a cam 94 mountedupon, and actuated by the power shaft 95 of the machine. A spring 40,engaging the slide 92, tends to move the slide downwardly to assist theclamping operation of the clamp. By the operation of the cam 9i and themechanism above described the clamp lever is moved first forwardly andthen downwardly at its forward end, at the proper point of the cycle ofoperation of the machine, so as to carry the clamp first forwardly andinto position over the bottle, and then down wardly into engagement withthe bottle.

The movement of the cam 9-1 and the power shaft 95 is not continuous,but these parts are thrown into operation intermittently upon theintroduction of each bottle into the machine. The shaft 95 is actuatedby a pulley 90 which may be belted to any suitable source of power. Thepulley is journaled loosely upon the rear extremity of the shaft 95 andnormally runs freely thereon, but by means of a one-rotation clutch thepulley is caused to impart a single rotation to the power shaft at eachoperation of the machine. The driving member of the clutch comprises aring 98 fixed within a recess in the hub 97 of the pulley. The drivenmember 99 of the clutch is fixed to the shaft 95 and provided withinclined surfaces as shown in Fig. 7. These inclined surfaces constituteseats for rolls 100 interposed between the driving ring 98 and theclutch member 99 and when the rolls .are wedged between their inclinedseats and the inner surface of the driving ring, the two members of theclutch are locked together and theshaft 95 is turned with the pulley 96.The rolls 100 do not bind the clutch members together, however, unlessthey are wedged in as first stated, and when not so wedged the pulley 96runs wild. The position of the rolls with respect to the clutch member99, .that is, the location of the rolls 011 their inclined seats isgoverned by a tightening ring 101 loosely mounted on the shaft 95 andprovided with a plurality of fingers 102 which project rearwardly fromthe ring into the spaces between the rolls, so as to engage the rolls.WVhen the tightening ring 101 is turned on the shaft 95 the fingers 102move the rolls 100 into or out of operative position as the case may be.As a' very slight movement only of the tightening ring 101 is necessary,a helical spring 121, having one end secured to the shaft 95 and theother end to the ring 101 is mounted between the shaft and ring and thisspring operates to maintain the ring 101 in such position with relationto the shaft 95, and the clutch member 99, that the rolls 100 are inoperative position and the clutch members locked together. The ring 101is provided with a cam 103 which normally engages a detent 104 mountedupon a rod 105 which slides horizontally in the frame of the machine. Solong as the lug 103 engages the detent 104 the ring cannot operate, andthe rolls are thus detained by the fingers102 and prevented fromoperatively engaging the clutch members. Then the retaining ring isreleased by disengagement from the detent, the spring 121 returns to itsnormal position and turns the tightening ring 101 on the shaft 95 andthereby the clutch is thrown into operation and continues operativeuntil the retaining ring makes a complete rotation and is again arrestedby the detent, when the shaft turns a short distance with relation tothe tightening ring, compressing the spring 121 and throwing out therolls.

The clutch detent is controlled by the bottle gage 15 hereinbeforedescribed. The bottle gage is mounted upon the forward end of ahorizontal sliding rod 107 which is pivotally connected, by means of agrooved collar. 108, with the upper end of a lever 109. The lever 109 ispivoted at 110.upon the frame of the machine and its lower extremity ispivotally connected with the clutch detent. A spring 106 normallythrusts the detent rearwardly into operative position. hen a bottle isplaced in the bottle rest and is pushed rearwardly against the gage 13,the gage is moved rearwardly, and, through the connection abovedescribed, the detent is moved forwardly out of engagement with the lugon the clutch retainer. After the labels have been afiixed to thebottle, and before the clutch has completed its revolution, the operatorwithdraws the bottle from the bottle gage, thereby permitting the spring106 to return the parts to their normal position so as to interrupt theoperation of the clutch until another bottle has been placed upon thebottle rest.

The wipers 1 1 are provided with bottleengaging extremities 59 of softrubber or other flexible material, formed to engage both the body andneck of the bottle. The wipers are mounted upon upwardly-extending arms111 mounted upon the forward ends of horizontal rock shafts 112. Therock shafts are mounted at the upper extremities of a yoke 113 which iscarried upon two vertical guide rods 114 moving in guides 115 on theframe of the machine. The yoke 113 is raised and lowered to actuate thewipers by means of a connecting rod 116 which connects the yoke with acrank pin on the cam 94:, so that at each rotation of the cam the wipersare raised above the bottle and are then lowered to cause them to engagethe bottle and the labels thereon.

During the upward movement of the wipers they are separated to hold themout of engagement with the bottle, and provision is made for moving theminwardly during the first part of the downward movement to bring theminto operative engagement with the bottle. T c this end arms 118 arefixed upon the rear ends of the rock shafts 112 and these arms carrypairs of cam rolls 119 engaging opposite sides of cam surfaces 120. Thecam surfaces 120 are formed integral with, and extend upers ascend toengage the labels in the label holders, and this relative movementcauses the arms 118 to be actuated by the cam surfaces 120 so as toswing the wipersinwardly over'the bottle, and during their continueddescent the wipers engage the labels at each side of the clamp and pressthe extremities of the labels smoothly against the bottle,

thereby completing the labelingoperation.

The above-described arrangement for moving the wipers and pickers inopposite directions at the same time secures mechanical balance betweenthe mechanisms by which these parts are actuated, thereby conducing tothe smooth operation of the machine and permitting the machine tooperate rapidly without excessive vibration.
